Ansa cervicalis. The ansa cervicalis is the biggest communicating loop of the cervical plexus. The neural loop contains motor nerve fibers from the anterior rami of C1 - C3. The ansa cervicalis is situated in front of the internal jugular vein in the carotid triangle and gives four deep muscular branches that supply motor innervation to muscles.

The ansa cervicalis, which innervates the infrahyoid muscles, is a neural complex in the neck formed by the combination of the ventral rami of the first three or four cervical spinal nerves. It is comprised of both superior and inferior roots. The superior root of the ansa cervicalis, the ramus descendens hypoglossi, travels with the.

The ansa cervicalis (or ansa hypoglossi in older literature) is a loop of nerves that are part of the first, second and third spinal nerve from the cervical plexus. It lies superficial to the internal jugular vein in the carotid triangle.The superior root of the ansa cervicalis is formed from cervical spinal nerve 1 of the cervical plexus. These nerve fibers travel in the hypoglossal nerve.

Cervical nerves are spinal nerves that arise from the cervical region of the spinal cord. These nerves conduct motor and sensory information via efferent and afferent fibers, respectively, to and from the central nervous system. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord.

The ansa cervicalis (or ansa hypoglossi in older literature [citation needed]) is a loop formed by muscular branches of the cervical plexus formed by branches of cervical spinal nerves C1-C3. The ansa cervicalis has two roots - a superior root (formed by branch of C1) and an inferior root (formed by union of branches of C2 and C3) - that unite distally, forming a loop.
